Hey all. Having the same problem with my OLED65B6T.

So far I've tried:

- Different router, ethernet cables & factory resetting it. When I connect via WIFI I get the same problem.

- Disable QuickStart+, hard shutdown (turn it off, unplug from the wall, manually press and hold the power on button at the bottom of the screen for 15 seconds)

- Opened up the back cover, but couldn't see any ribbon wires that need uncrimping - see photos attached. The cable I circled I removed & cleaned with electronic cleaner.

 

Things that I might try later:

- Replace RF module board - they go for about $50 on aliexpress

- Get an ethernet to usb adapter - anyone know which one works on the B6?

- Replace the main board - prefer not to lol

 

This is so frustrating as I upgraded from my 10 year old 40" LG TV that had zero issues. I'm hoping I can fix it, otherwise I'm going to avoid LG products in future.

Have you given those two ribbon cables on the left a clean? I dont think having a ribbon cable with a bend is the issue, their ribbon cables just seem to be prone to oxidizing badly. Wouldn't hurt to at least try unplugging and replugging anything you can see a few times?

Just wanted to thank everyone who shared their solutions here. My 65UJ6200 TV was also in pretty bad shape. Youtube and  amazon prime video would freeze the picture but the audio would keep playing. And then after a second the picture would speed up to catch up to the audio. I kept getting LAN disconnect and reconnect messages. My wifi also didn't show any networks and sometimes just crashed.

I took apart the TV just removing 19 philips screws. I then gently unplugged the ribbon cables, some of which were a little stuck, and gave them a wipe with rubbing alcohol. My wifi connector wasn't a ribbon cable when it connected to the wifi module, so I just unplugged and replugged that connector a few times. I also didn't mess with the 90 degree bend, since it seemed normal.

Everything is fixed! If you're having this issue, seriously try taking it apart and cleaning the ribbon cables. I wouldn't be surprised if just disconnecting and reconnecting them would fix it.
